My interest is not for movies, but for projecting high quality images, probably from the PC or laptop.

Hi Woodbe

I really can't answer that as I have never seen a 1024x768 LCD projector working and I have not operated my projector through my computer. All I know is that the resolution is excellent on mine.

The best thing is to have a look on the LumenLab Forum and it is worth paying the $19.95USD to get full access to the whole forum because the information is totally invaluable.

The latest design they are using is with a 17" LCD panel and the resolution is fantastic. Since I built mine the improvements LumenLab have made are very substantial and they are experimenting all the time.

If you have a look here you can see the resolution out of a 17" panel with the latest lenses they have available.

Barry,

I noticed you checked the temprature of your pj. Have you included some sort of protection that turns the light off when the temp gets to high?

Also what environment are you using it in, ie airconditioned? Just thinking how it would go during the hot summer with ambient temps much higher than this time of year.

Great find though. I think this may be my next project.

I have a temperature gauge that records both the temperature in the light box and also the temperature at the LCD screen. I live in an area where the evening summer temperatures don't go much above 30 degrees C and that is pretty rare and the highest the temperature has gone at the LCD is 36 degrees.

I don't have a cutout for the light controlled by the temperature but I do have it wired so that if the fan is turned off the light will go out also.

I don't have air-conditioning in the house but I do have a ceiling fan above the projector.

I also don't use it during the daytime.
